This document discusses achieving a big data analytic platform using the Lambda architecture on cloud infrastructure. It begins by explaining why moving to the cloud provides benefits like elastic scaling, reduced operational overhead, and increased focus on innovation. Common cloud services at Trend Micro like an analytic engine and cloud storage are then described. The document introduces the Lambda architecture and proposes a serving layer as a service. Key lessons learned from building big data solutions on AWS include the pros of unlimited scalability and easy disaster recovery compared to on-premises infrastructure.
